To all whom it may concern: 1

Be it known that 1, WILLIAM CARSON DEUBERRY, a citizen of the United States, residing at Greenfield, in the county of Weakley and State of Tennessee, have invented new and useful Improvements in Roll-Paper Holders and.Outters, of which the following is a specification;

This invention relates to paper roll holders and cutters used for serving and severing roll paper for wrapping and other purposes; and the object thereof is to provide a device of such class with means in a manner as hereinafter set forth for projecting the web from the cutters after a portion has been severed so as to enable the web to be readily grasped when it is desired to out another length.

Further objects of the invention are to provide a roll paper holder and cutter which shall be simple in its construction, strong, durable, eflicient in its use, readily set up with respect to a counter, conveniently operated and inexpensive to manufacture.

With the foregoing and other objects in view themvention consists in the novel construction, combination and arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings, wherein like characters denote corresponding parts throughout the several views and in which Figure 1 is a perspective view of a roll paper holder and cutter in accordance with this invention; Fig. 2 is a top plan of the grippers; Fig. 3 is a longitudinal sectional view showing the adaptation of the holder and cutter in connection with a counter and further showing the position of the elements during the act of severing the web, and, Fig. 4 is a like view showing the position of the parts after a portion of the web has been severed and further showing the web as projecting from the cutters so that the web can be readily grasped when it is desired to sever another length.

Referring to the drawings by reference characters 1 denotes a receptacle in which is j ournaled a roll of paper 2. The front and rear walls of the receptacle 1 have the inner faces thereof formed with an inclined groove 3 the groove starting at its top from a point midway between the center and one end of the wall and terminating at its bottom approximately centrally of the wall. The bottom of each of the grooves 3 forms a bearing 5 for the journal 6 of the roll. By such an arrangement a roll of paper can be readily inserted and removed from the receptacle when occasion so requires. Within the grooves 3 is also mounted a gravity movable pressure-roller 7 which bears against the outer roll so as to keep the journal 6 of the roll in contact with its bearings 5, and further to keep the windings of the web in close contact. Withinthe receptacle 1 is positioned a tension bar 8 and which is arranged over the roll. The web 9 is adapted, as it unwinds 0H the roll, to contact with the bar 8.

Mounted upon the front wall of the receptacle 1 is a bracket 10 having at each end vertically-extending apertured ears which are indicated by the reference characters 11 and 12. The ears 11 and 12 are alternately disposed with respect to each other. A like construction of bracket is mounted upon the top of the rear wall of the receptacle 1, the same reference characters being applied to such form of bracket. The brackets 10 are arranged opposite one another. Pivoted, as at 13,. to each of the ears 12 is a bell crank lever 13, one arm being longer than the other, the elongated arm being indicated by the reference character 14 and the shorter arm by the reference character 15. Normally the arm 14 extends upwardly and inwardly at an inclination, while the arm 15 extends in a horizontal manner. Pivoted as at 16 to each of the ears 11 is a bell crank lever 16 the longer arm of which is indicated by the reference "character 17 and the shorter arm by the reference character 18. Normally, the elongated arm 17 extends upwardly and inwardly at an inclination, but in an opposite direction with respect to the direction in which the arm 14 extends. The shorter arm 18 extends in a horizontal direction, but in an opposite direction with respect to the direction in which the arm 15 extends. The levers 13 are arranged opposite each other and the levers 16 are ar ranged in a like relation. The arms 15 of the levers 13 are each provided with pins 19 which extend through an elongated slot 20 formed in the arms 18 so that there will be formed by such pins and slots a loose connection between the arms 15 and 18. The arms 14 and 17 are connected together by an extensible and contractible spring 21, the latter having one end connected as at 22 to the arm 14 and at its other end attached to the arm 17, as at 23. The function of the spring 21 is to retain the arms 17 in contact with each other. When the arms are separated in a manner as hereinafter set forth it is against the action of the pull of the springs 21 so that the moment the arms 14 and 17 are released the springs 21 will cause them to move towards each other. Secured to the arms 14 at the top thereof is a cutting member 24 and a cutting member 25 is also secured to the arm 17 at the top. The cutting members 24 25 are normally drawn towards each other through the medium of the springs 21.

Arranged below the cutting members 2425 and within the arms 14, 17 are the vertically-extending grippers 26-27, which are formed of flat strips having a rubber covering 28. The grippers 28 not only act as a means to grip the web and retain it in a vertical position, but further act as a means to project a portion of the web past the cutting edge of the members 2425 so that the web can be readily grasped when it is desired to sever a length thereof. The grippers 2627 at each end are slotted, as at 29 the slots of one gripper opposing the slots of the other gripper, and through a pair of opposing slots 29 extends a coupling member 30, which is adapted to prevent the separation of the grippers with respect to each other. Each of the coupling members has enlarged ends 31 so that the grippers cannot be pulled therefrom. The gripper 26 as well as the gripper 27 at each end thereof is formed with an outwardly extending apertured ear, the ears for each gripper being indicated by the reference characters 32, and 33. Pivoted to each of the ears 32, 33 of the gripper 26 is a downwardly-extending link 34 which is pivoted at its lower end as at 35-to the inner end of a lever 36, the latter being pivoted intermediate its ends as at 37 to an arm 14. The outer end of the lever 36 is connected by a link 38 to the free end of an arm 18. Pivoted to each of the cars 32, 33 of the gripper 27 is a link 39 which has its lower end pivotally connected as at 40 to the inner end of a lever 41, the latter being pivotally connected intermediate its ends, as at 42, to an rm 17. The lever 42 at its outer end is connected through the medium of a link 43 to the free end of an arm 15. The links 32 are arranged opposite the links 39 and the link 32 is connected to a link 39 through the medium of an extensible and contractible spring 44. The operation of the device is as follows :It will be assumed that the device is in the position shown in Fig. 4 with the end of the web 9 projecting from the cutting members 24, 25. The operator pulls the web to one side so that the parts will assume the positions shown in Fig. 3. By pulling the web in the direction as indicated by the arrow in Fig. 3 the arms 17 are shifted against the wall 45 of the opening 46 formed in the counter 47 with which the device is arranged in operative relation. When the arms 17 are shifted the arms 18 are elevated which in turn elevate the links 38, these latter shifting the levers 36 so that the inner ends thereof will be lowered carrying the links 34 therewith, these latter lowering the gripper 26. When the arm 17 is moved in the direction stated the pins 19 will be engaged by the walls of the slots 20 and such action will elevate the arms 15 thereby shifting the arms 14 against that portion of the wall 45 of the opening 46 which is opposite the portion of the wall engaged by the arm 17. When the arms 15 are elevated the links 43 will also be elevated shifting the levers 43 upon their pivots and lowering the gripper 27, but the extent of lowering the gripper 27 will not be as great as that of the gripper 26. The grippers, however, will both be moved in close proximity to the arms 17 so that the web below the grippers will extend at an inclination. The separating movement of the arms 17 will be against the pull of the springs 21 and the shifting of the links 34, 39 will be against the pull of the springs 44 so that when the length of the web is cut and the web released the arms 14, 17 will, through the action of the springs 21, be drawn towards each other so that the arms l5, 18 will be lowered, which action will cause the elevating of the grippers to the position shown in Fig. 4 and consequently a portion of the web will be projected past the cutting members 24, 25 so that the end of the web can be readily grasped by the operator when it is desired to sever another length. This is evident owing to the length of the web between the cutting member and the grippers when the arms 14 and 17 are separated in a manner as shown in Fig. 3, the length of such portion of the web being such that when the grippers are moved to the position shown in Fig. 4 the web will be forced past the cutting members. Owing to the manner in which the links 34, 38 and 39, 43 are mounted with respect to the levers 36, 41 and also with respect to the grippers and bell crank levers it is evident that when the arms 14, 17 are released from the position shown in Fig. 3 that the grippers will be caused to move vertically and assume the position shown in Fig. 4, consequently causing the end of the web to project past the cutting members 24, 25.
